Pendolino (from Italian Pendolo ['pɛndolo] "Pendulum" and -ino, a diminutive suffix) is an Italian family of tilting trains used in Italy, Spain, Portugal, Slovenia, Finland, the Czech Republic, Slovakia, the United Kingdom, Switzerland, China and shortly in Romania, Ukraine and Russian Federation. It was developed and manufactured by Fiat Ferroviaria, which was taken over by Alstom in 2002.

The idea of a tilting train became popular in the 1960s and 1970s when various rail operators, impressed by the high-speed rail services being put into place in France and Japan, wondered how they could similarly speed up travel without building a dedicated parallel rail network (as those two countries were doing). By tilting, the train could round curves designed for slower trains at higher speeds without causing undue discomfort to passengers.
